the program structure is
appComponent is the parent element

under
tableComponent1
tableComponent2

now use routing to switch between these two pages

the code in the original appComponent.html is
< / app-table-data >
< / app-table-data-2 >

then, because you want to change the route switching code to this
< router-outlet > < / router-outlet >

but I did pass the list parameter to Component

so change the code to this < router-outlet [list] = "list" > < / router-outlet >

the result is bad. Is it impossible to pass parameters with router? What"s the solution? ask the god for help
